寻找并配制苯甲腈和正十四烷溶液的临界温度和临界组成，用折射率方法测定共存曲线.在离临界温度11.4 K范围内测定了温度-折射率数据，通过计算临界指数β和指前因子B，结果与3D-Ising模型的理论值一致.

The critical components and critical temperature of( benzonitrile + tetra -decane)have been found and made up of. The temperature-refractive index( T,n)coexistence curve of the critical binary solution has been determined within 11. 4 K from the critical temperature by measuring refractive index. The critical expo-nent β and the critical amplitude B have been deduced by the linear least-squares fitting,and the result is con-sistent with the theoretical prediction of the 3D-Ising model.
